REVOLVING DINING-ROOM FLOOR.

Specification of Letters Patent.

Patented May 18. 1915.

Application filed May 21. 1914. Serial No. 840,138.

This invention relates to improvements in floors. and particularly tofloors for dining rooms. and has foran object to provide an improvedconstruction and arrangement whereby there will be presented stationarysections for accommodating tables. and movable sections for alsoaccommodating tables. -A further object of the invention is to provide aflooring with rotating sections designed to accommodate tables. saidrotating sections being provided with serving tables in the centerwhereby the waiters need not move from the moving platform during theirwork.

In carrying out the objects of the invention a flooring is providedwhich may be supported in any desired manner. and which may besurrounded with side walls or left open, as preferred. Arranged as partof this flooring are one or more rotating sections whereby the flooringwill present stationary sections and i'otat'ing sections, Tables arearranged on all of the sections 'so thatpersons may be served on thestationary part of the llooi or on the movable parts. In order that thewaiters -may properly serve the patrons on the movable parts of thefloor a serving table is arranged centrally of each of the moving parts,and ea'chserving table is provided with a dumb waiter preferablyoperated from the mov able section to the floor beneath. This will allowthe waiters to move back and forth from the serving table to theirvarious tables even though the section rotates continually. This couldnot be readily done if a serving table was arranged on one of thestationary sections of the floor.

In the accompanying drawingsFigure 1 is a top plan view of a floorembodying the invention, the same being shown inclosed; Fig. 2 is anenlarged fragmentary sectional sect-ion shown in Fig. 2: Fig. 4 is anenlarged side elevation of the serving table embodying certain featuresof the invention. Fig. 5 is a detailed fragmentary sectional viewthrough a slightly modified form of invention to that shown in Fig. l.the same being taken approximately on line 5-5 of Fig. (i: Fig. o is atop plan view of the structure shown in Fig. 5. part being broken away.

Referring to the accompanying drawings by numeral. 1 indicates a wall ofany desired structure which is provided with suitable doors and windows.the same not forming any part of the present invention. Inclosed by thewalls 1 is a lloor 2 provided with a stationary part and movable parts 4and 3. it will be evident that a greater or less number of moving partscoulddie provided without departing from the spirit of the invention.Arranged on the station ary part I; are tables 1 and T for the use ofpatrons. and also serving tables for the use of the waiters in preparingthe dishes for serving the patrons. the entire arrangenn-nt being theusual furniture provided for restaurants. cafes and the like. the movingparts or sections -l and 5 are tables 9 for the patrons. while arrangedcentrally of the sections -l and 3 are serving tables 1H for the use ofthe waiters. The

serving tables 10 are each provided w th a 35 serving tables 10 the sameare provided with central shelves l3 and a top 14 together with drawers15 and closets 16. The drawers 15 and closets it are adapted to containlinen. silver and other things necessary in properly serving the patronsof the dining room.

On top of the serving table may be arranged an ornamental centerpiece 17for givinga finished appearance to the entire structure.

Arranged on 80 Between the moving !-'(([i ll 90 In forming the rotatingsections 4 and 5 view approximately online'-22 of Fig. 1:

a suitable flooring portion 18 is provided Fig. 3 is a bottom plan viewof. the rotating supported by suitable beams 19 (Fig. '2) to which beamsare secured tracks 20 and 21. Track 20 is provided with a rack 22, whichrack is adapted to mesh with a gear-wheel 23. Gear wheel 23 is rigidlysecured to shaft 24 which carries a beveled gear 25 meshing with gear26. Gear 26 is rigidly secured to shaft 27, to which power istransmitted from motor 28 by gears '29 and 30. In addition to beveledgear '25 meshing with ar 26 a second beveled gear 31 also meshes with-geart26, said gear 31 being rigidly secured to shaft 32 which carries agear wheel 33 meshing with rack 34 on track 35 of table 5. Track 20 isrigidly connected with table 4. By this construction and arrangementwhenever motor 28 is operated both of the movable sections 4 and 5 willbe rotated. In order to properly support the sections 4 and 5 aplurality of rollers 36 and 37 are provided for each of the movingparts, said rollers being supported by tracks 38 and 39 carried bysuitable supports of any desired kind, as for'instance beams 40.' Therollers 37 are provided with flanges so as to guide the sections intheir rotary movement and prevent any contact of the moving sectionswith the stationary sections though these section's are very closetogether as clearly shown in Figs. 1 and 2.

In operation when the eating house is being used, the patrons may passon to floor 2 to any ofthe doors of wall 1, and may use any of thetables 6 or'7 on the stationary part of the floor, or may pass on toeither of the rotatingsections 4 and 5 and use any of the atrons tablesarranged thereon. Meanwhile the sections 4 and 5 are rotating slowly sothat there is no trouble for the patrons or anyone passing on to therotating sections or off the rotating sections. By providing rotatingsections as described a person using a table on .one of the rotatingsections may see all ofthe other patrons in the room as the viewpoint iscontinually changing by reason of the rotation of said sections.

In Figs. 5 and 6 a modified form of the .invention is shown in which theusual floor 2 is not disturbed except for the provision of an opening 41through which a dumbwaiter is adapted to pass. Also, an aperture 42 isprovided for the a'pertu'red shaft 27. As clearly shown in Fig. 5 thetracks 20 and 39 are arranged above the floor 2, track 39 beingpreferably arranged directly on the floor and track 20 as near the flooras possible 'sothat the space between the original floor 2' and theauxiliary floor 2" is comparatively small. The auxiliary floor 2" isprovided with rotating sections 4 and 5 and a stationary portion 3.whichhas provided thereon a dancing floor 12 similar to the structure shownin Fig. 1. The only difl'erence between this form of the invention andthat shown in Fig.1 is the arrangemcnt of an auxiliary floor on apermanent floor so that when setting up the invention in a building itis not necessary to tear up the original lioor or otherwise mutilate thehuilding. In connection with the rotating sections 4 and 5 it will benotedthat these are rotated in opposite directions and preferably at aslowrate of s)eed. Preferably one of the sections or plat orms isrotatedfaster than the other. This is to allow the occupants of the rotatingsections to see each other as well as see the occupants of the tables onthe stationary part of the floor. In order to assist the waiters whenthe food is brought from one end of the room and not through thedumbwaiter a plurality of lights 43 are provided on the serving table.In fact there is a light 43 for each section of the serving table sothat if desired one waiter could be assigned to each light andconsequently all three tables as shown in Figs. 1 and 6. It is evidentthat a greater or less numberof tables could be provided for each lightwithout departing-from the spirit of the invention. In case a waitershould leave'the rotating platform for something the platformwouldcontinue to rotate during his absence and consequently his tableswould be at a difi'ercnt point when he returned. Instead of searchingfor his tables he would move to his particular light and from this tohis tables, thus easily determining where his tables were located.

In Fig. 6 no tables are shown on the stationary part of the floor but itis evident that the same may be provided without departing from thespirit of the invention as this figure together with Fig. 5 merelyillustrates the adaptability of the invention to a building withoutmutilating the floor to any considerable extent.

What I claim is- 1. In a dining room floor of the character described, astationary section, a plurality of rotating sections, a plurality oftables arranged on said stationary section, a dancing floorstructure'arranged on said stationary section between said rotatingsections, a plurality of tables arranged on each of said rotatinsections, a serving table arranged centra 1y of each of said rotatingsections and rigidly secured thereto so as to rotate therewith, and adumb waiter arranged centrally of each of said serving tables wherebythe serving tables may be supplied during the rotation of the rotatingsectlons.

2. In a dining room floor of the character described, a stationarysection for receiving tables,- a plurality of rotating sections adaptedto receive tables, a servin table arranged in the center of each of sairotating sections and rigidly secured thereto so as to rotate therewith.a dumb waiter arname to this specification in the prawns of rangedcentrally of each of iaid two subscribing witnesses. tables whereby theserving t-a les ma 1' 1 1 supplied notwithstanding the rotatin 'ofALTOINL MABTZOLF said sections. and means operating on said Witnesses:sections for rotating the same.
